Polyplastics' latest material development efforts target electric vehicle (EV) applications
THE electrification of cars is transforming the automotive industry and Polyplastics Co., Ltd., a leading global supplier of engineering plastics, is responding with innovative resin products which are successfully penetrating the electric vehicle (EV) market as a superior alternative to metals. The company's Duranex PBT and Durafide PPS materials - targeted for engine peripheral parts such power control units (PCUs) – deliver high insulating properties, lower water absorption, and meet harsh operating conditions (-40°C to 150°C, up to 95% relative humidity).
Polyplastics' Duranex PBT CG7030 provides lower water absorption and high tracking properties (CTI: 600V) for high-voltage parts such as PCUs. The material ensures high reliability for high-voltage parts that do not gain enough creepage distance. Water and salt can penetrate high-voltage parts and cause tracking issues so materials with high CTI values are required.
Polyplastics also offers Durafide PPS 6150T73, which provides high heat shock resistance, strong dimensional stability, and excellent heat and chemical resistance for metal insert molded applications for electric vehicles. Previous material technologies suffered from lower heat shock resistance when moldability (flowability) increased.
Polyplastics is also exploring new materials to replace metal in PCU housings. Thermoplastics would provide lighter weight and improved productivity, however, other key requirements include strength, dimensional stability, electromagnetic shielding, and thermal conductivity. Specifically, Polyplastics is currently developing materials with electromagnetic shielding properties. The company is also targeting its material development work for other EV applications such as motors and batteries. The Polyplastics Group is a global leader in the development and production of engineering thermoplastics. The Group's product portfolio includes PBT, PS, polyoxymethylene (POM), liquid crystal polymer (LCP), and cyclic olefin copolymer (COC). With more than 50 years of experience, the company is backed by a strong global network of R&D, production, and sales resources.

Milliken's Millad NX 8000 clarifier offers sustainability and performance benefits
IN April, Milliken & Company will begin building the largest clarifier plant in its history in Blacksburg, South Carolina, USA. The world-class plant is due to begin operations in 2020 and will boost capacity of Milliken's Millad NX 8000 clarifier by approximately 50 percent. The expansion is needed to meet fast-growing global demand for this polypropylene additive that is helping users to realize significant sustainability and performance advantages. Millad NX 8000 offers many sustainability and performance advantages over previous polypropylene clarifier generations for plastic molders and brand owners who use it. “In contrast to previous generation clarifier technologies, Millad NX 8000 has the potential to significantly reduce greenhouse gas emissions for plastic manufacturers,” says Zach Adams, global product line manager for Milliken's Plastic Additives business. “Our propriety technology improves the aesthetics and processability of polypropylene, a plastic which is lightweight, has a low carbon footprint and almost always performs better than less sustainable plastics in a life cycle analysis.”
Underwriters Laboratories (UL) has validated that the processing of resin containing Millad NX 8000 requires lower energy consumption than other polypropylene that uses third-generation clarifiers, allowing the UL eco-label to be used on those products. Lower processing temperatures are benefitting users with energy savings.
“Brand owners and packaging producers are clearly seeing how Millad NX 8000 can contribute to improved environmental and manufacturing results. It is one of the most successful products in the history of plastic additives, and arguably the most important in the past 30 years,” according to Allen Jacoby, vice president for Milliken's Plastic Additives business. Unprecedented global demand for the technology has prompted Milliken to expedite the construction of its new facility by two years. Demand for Millad NX 8000 is growing in every geographical region and across many end-use markets, with the strongest growth in Asia. Milliken's investment will enable the company to better serve its customers worldwide and meet dynamic market requirements. Millad NX 8000 creates opportunities to replace less sustainable plastics such as polystyrene and PVC with NX UltraClear PP, a type of polypropylene that can only be produced using the Millad NX 8000 clarifier. “Millad NX 8000 clarifier technology represents a step forward in both environmental and product performance,” Jacoby notes. “Milliken is asking other companies in the plastics supply chain to join us in stepping up to the plastics end of life challenge.”

'Skin-like' flexible polymer developed for regenerative medicine
A bioresorbable polymer that snaps back to its original shape, even after being stretched 10 times its initial length, has been developed by Toray Industries Inc. (Tokyo). The company also has identified a technology to accelerate degradation of the polymer by means of hydrolysis. The material would benefit regenerative medicine and other medical applications as well as various industrial uses.
A novel co-polymerization method involving lactide, dimers of lactic acid and caprolactone enabled Toray to significantly reduce crystallinity and impart flexibility and rupture resistance to the material. Furthermore, by controlling hydrolysis of the polymer, Toray was able to increase the decomposition speed tenfold.
Tissue reconstruction treatment is one medical application that would benefit from this polymer with “skin-like” flexibility. Polymer-based medical materials are typically used as temporary scaffolding while the injured flexible tissue regenerates, explained Toray in its March 14 announcement. The material resorbs once the healing process is complete, eliminating the need for additional surgery.
In a desk study, the outer surface of a 3-mm-diameter vascular graft made from a polyester fiber was coated with the polymer. The material didn't buckle even when the device was bent, and it flexibly followed the movement of the vascular graft, said Toray.
The company said that it will pursue further development of its bioresorbable polymer as a scaffolding material in regenerative medicine involving blood vessels, skin, digestive and urinary organs, and muscles.
Chemical foaming agents for injection molding applications
BERGEN International has a proven line of Chemical Foaming Agents to help one maximize cost savings in the Injection Molding processes. Generally used for weight reduction, sink mark removal and warp reduction, Bergen International Foamazol CFAs are added to the injection molding process in the same manner as any other additive master batch.
Use of Foamazol products permit molders to increase shot speeds, reduce pack and hold pressures and times, and to reduce clamp tonnage resulting in reduced cycle times (reductions of as high as 30% have been achieved). Also, the addition of Foamazol CFAs allows for a reduced shot size which results in weight reduction of the parts. A 10% reduction in the weight can easily be achieved with most Injection Molded resins, and it is often possible to achieve upwards of 20-30% weight reduction with proper process design.
In addition, sink mark removal and warp reduction are other benefits that can be gained through the use of Foamazol Chemical Foaming Agents. One grade in particular, Foamazol 62, has been proven in certain cases to eliminate sink with a Class A surface.
Whether you require reduced cycle times, parts weight reduction, sink mark removal, warp reduction, or are striving for a Class A finish; Bergen can work with you to identify the best CFA for your application. They also have a comprehensive line of Endothermic, Exothermic and Endo/Exo blend CFAs; with products available for a wide variety of resins, processing temperatures, processes, and application environments.
